ZStack(alignment: .bottomTrailing) { // <- new Image(decorative: resort.id) .resizable() .scaledToFit() Text(resort.imageCredit) // <- new .font(.footnote) // <- new } // <- new |
for 2nd challenge
for load

init() { // load our saved data if let data = UserDefaults.standard.data(forKey: saveKey), let decodedData = try? JSONDecoder().decode(Set<String>.self, from: data) { resorts = decodedData } else { self.resorts = [] } } |
for save

func save() { // write out our data let data = try? JSONEncoder().encode(resorts) if let encodedData = data { UserDefaults.standard.set(encodedData, forKey: saveKey) } } |
for 3rd challenge:
On top of 3rd challenge, I added how many resorts are there for each condition. Ex: how many resorts are there for size small.
create ResortList class
ResortList.swft
